What does CAD stand for in engineering design?

In engineering design, CAD refers to Computer-Aided Design. This technology is widely utilized by engineers, architects, and drafters to create precision drawings and technical illustrations. CAD software allows users to design in both 2D and 3D, enhancing productivity and accuracy as opposed to manual drafting.

With CAD, modifications can be easily made without the need to redraw everything, which streamlines the design process and increases efficiency. Additionally, CAD software often includes tools for simulations, analysis, and documentation, facilitating a comprehensive approach to design that integrates various aspects of engineering. This is pivotal in modern engineering where accurate representations of structures or components are essential for successful project execution.

Other options, while they may seem plausible, do not represent widely accepted terms or practices in the engineering design field. Therefore, Computer-Aided Design is the clear and correct term that captures the essence of modern engineering design practices.
